An "int" is just any whole number: 0, 1, 2, 13, -7, etc.

But a "boolean" can only represent two things, "true" and "false" (or taken as a number, only 1 and 0).

This makes them useful for different purposes. For example, if you wanted to count something, you might use an int; but if you were keeping track of the state of a light switch, you'd likely use a boolean.
